Norway's currency is the krone (plural: kroner), abbreviated NOK, Nkr, or Kr.

One krone is divided into 100 øre, but the only øre coin you'll deal with is the 50 øre (1/2 krone) coin, so you needn't worry much about øre. Think kroner and the occasional half-kroner.

You'll see krone notes/bills in denominations of 50, 100, 200 and 500 kroner. Besides the 50-øre coin, there are coins of 1, 5, 10 and 20 kroner.

Norway does not use the euro, though euro bills are accepted as a convenience (and usually at a poor rate of exchange) in some touristy places—especially shops.
